Since contain both numbers and variables, there are two steps to find the GCF (HCF). Find GCF for the numeric part then find GCF for the variable part.
Steps to find the GCF for :
1. Find the GCF for the numerical part
2. Find the GCF for the variable part
3. Multiply the values together
Find the common factors for the numerical part:
